I tried searching this forum for post about this topic, but wasn't able to find any resolutions. I gather what I'm experiencing is an alternator whine? Basically, when I'm on the tuner or aux sources, the more I press down on the gas pedal, the higher the pitch of the whine I'm hearing. It's quite annoying. What's the cause of this? What can I do about it? And is there a reason that the whine is louder some times more than others?

Thanks for your help.
